SPECIFICATION forming part of Letters Patent No. 706,980, dated August12, 1902.

Application iiled lViay 3, 1902. Serial No. 105,761. (No model.)

To @ZZ whom t r11/ty concern:

Be it known that I, PETER W. MARTIN, a citizen of the United States, anda resident of Thumb Lake, in the county of Charlevoix and State ofMichigan, have invented a new and Improved Snow-Plow, of which thefollowing is a full, clear, and exact description.

This invention relates to improvements in plows for removing snow fromroads or the like; and the object is to provide a snowplow that may bequickly and easily adjusted to discharge snow at both sides or todischarge snow at either side," and, further, to vso arrange the partsthat the horses propelling the device are placed at the back, so thatthey are not compelled to walk in vdeep snow, as would be the case werethe horses drawing at the front. p

I will describe a snow-plow embodying my invention and then point outthe novel features in the appended claims.

Reference is to be had to the accompanying drawings, formingapart ofthis specification,

in which similar characters of reference indicate corresponding parts inboth figures.

Figure 1 is a side elevation, with a portion broken away, `of asnow-plow embodying myV invention; and Fig.' 2 is a plan view. thereof.

The body of the snow-plow comprises runners 1, secured to which is aplatform 2.. The plow proper Vcomprises a point or nosepiece 3, to thelaterally-extended divergent portions 4 5 of which the moldboards 6 V7are hinged, so as to swing inward and outward. The point and moldboardsare made of suitable metal, and theV moldboards are vertically curved,as clearlyindicated. Arms 8 are connected at their forward ends to thepoint or nosepiece and at their rear ends have pivotal connection with aplate 9, mounted to turn on the platform 2, and which may be termed theturn-table.

Arranged on the turn-table is a segmentrack 10, pivoted to which `is alever 11, having a spring-pressed dog for engaging with the rack, and alink or bar 12 connects the lever 11 with the point or nosepiece. Bymeans of this lever and its connection with the point or nosepiece theplow may be raised to a substantially vertical position when it isdesired to draw the device along without operating the plow. From themoldboard 6 a `while the otheris moved outward when it is desired tomove snow at one side only. The turn-table 9 is provided with asegmental rack 19, with which a pinion 20 meshes. This pinion 20 isarranged between the platform 2 and a metal strap 21, and it isconnected to a steering rod or shaft 22, having a hand-wheel 23 at itsupper end. This steering rod or shaft has a bearing in the strap 21, andat its lower end it may have a step-bearing in the platform 2. By meansof the pinion 20 and the rack 19 the plowpoint or nosepiece may bedeflected laterally in order to steer the plow through the snow, and theparts .may be held as adjusted `by means of a pawl 24, engaging with atooth of the pinion 20, as clearly shown in Fig. 2.

Extended rearward from the plow is a pole 25, to which the horses are tobe attached. From the forward end of the pole 25 arms 26 extend and arepivotally connected to lugs 27 on the platform. To hold the poleyieldingly in position,a spring-plate 28 is attached lto the platform 2and at its freeend passes loosely through a loop 29, attached to thepole.

Having thus :described my invention, I claim as new and desire to secureby Letters Patent- 1. In a snow-plow, a body portion having runners, aplow-point or. nosepiece, rearwardly-extended divergent moldboardshaving swinging connection with 'said point or nosepiece, means forswinging theplow laterally with relation to the body portion, and meansfor adjusting the moldboards inward and outward, substantially asspecified.

2. A snow-plow comprising a body portion having runners, a turn-tablemounted on the body portion, means for rotating said turntable, a plow,arms extended from said plow IOO and having pivotal connection with theturntable, a lever mounted on the turn-table, and a link connectionbetween said lever and the plow, substantially as specified.

3. A snow-plow comprising a body portion having runners, a-plowconsisting of a point or nosepiece, moldboards arranged to swinglaterally on said point or nosepiece, and means for moving saidmoldboards inward and outward independently one of the other,substantially as specified.

4f. A snow-plow comprising a body portion having runners, a draft-poleextended rearward from the body portion, a turn-table arranged onthebody'portion, means for rotating the turn-table, a plow consisting of apoint and moldboards mounted to swing lat-
